Large-scale concurrent live streaming with chat, QR attendance, and channel access control. The 18,000 figure is a published test result; guaranteed standing capacity is sized separately by contract.
Screen freezes past 500 viewers. Every company-wide townhall starts with "how many can it handle?" anxiety.
Tracking attendance manually. After each live session, another hour spent cross-checking attendance in spreadsheets.
No meaningful interaction. "Any questions?" is met with silence in chat, and the session becomes a one-way broadcast.
